  2. 1. Electrochemical Investigation of the Reaction Mechanism in Lithium-Oxygen Batteries

    Author : Jonas Lindberg; Göran Lindbergh; Ann M. Cornell; Bryan McCloskey; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-Oxygen Batteries; Lithium Mass Transport; Oxygen Solubility; Reaction Rate Law; Reaction Mechanism; Electrode Passivation; Ultramicroelectrodes; Electrochemical Quartz Crystal Microbalance; EQCM; Chemical Engineering; Kemiteknik;

    Abstract : Lithium-oxygen batteries, also known as Lithium-air batteries, could possibly revolutionize energy storage as we know. By letting lithium react with ambient oxygen gas very large theoretical energy densities are possible. READ MORE

  4. 2. Oxidation and reduction reactions of the water-oxidizing complex in photosystem II

    Author : Long Vo Pham; Johannes Messinger; Imre Vass; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photosystem II PSII ; oxidation; reduction; flash induced oxygen evolution pattern FIOP ; water; oxygen; global fitting program GFP ; thylakoids; fysikalisk kemi; Physical Chemistry;

    Abstract : The oxygen that we breathe and food that we eat are products of the natural photosynthesis. Molecular oxygen is crucial for life on Earth owing to its role in the glycolysis and citric acid pathways that yield in aerobic organisms the energy-rich ATP molecules. READ MORE

  5. 3. Air-sea exchange of O2 and CO2 : Processes controlling the transfer efficiency

    Author : Andreas Andersson; Anna Rutgersson; Brian Ward; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; air-sea flux; oxygen; transfer velocity; water-side convection; Arctic; UVCN; Meteorologi; Meteorology;

    Abstract : World oceans cover more than 70% of the earth surface and constitutes a major sink of atmospheric CO2. Two of the most important gases in the marine carbon cycling are O2 and CO2 and hence accurate descriptions of the air-sea gas exchange of these gases are crucial. READ MORE

  6. 4. Infrared spectroscopy of O2 and N2 adsorption on the clean and hydrogen covered Pt(111) surface

    Author : Kristian Gustafsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared Spectroscopy; Adsorption; Hydrogen; Nitrogen; Pt 111 ; Oxygen;

    Abstract : This thesis is devoted to the investigation of O2and N2 adsorption on the clean and the hydrogen covered Pt(111) surface. Using infrared reflection absorption spectroscopy (IRAS) both physisorbed and chemisorbed molecular adsorptionstates have been identified and characterized via theircharacteristic internal vibration spectra.
